3 Claims. 1

This invention relates to screens and has for its object to provide awindow or other screen formed of a series of vertically connected slats.

Another object of the invention is to provide a screen or window shadeformed of a series of vertically supported and horizontally movableslats.

A further object of this invention is to provide a slatted shade orscreen through which objects on the outer side thereof may be clearlyseen without having to closely approach the same.

A still further object of the invention is to provide a slatted screenoperated by a toggle device from which the screen is suspended.

Other features and advantages will become more readily apparent from thefollowing description and the accompanying illustrative drawings inwhich:

Figure 1 is an elevational view of my improved screen shown in closedposition and attached to a window,

Figure 2 is a similar view, the slats being shown open,

Figure 3 is a similar view, the screen being shown drawn back,

Figure 4 is a vertical sectional view of a wall having a window thereinequipped with this invention.

Figure 5 is a detail of an operating means,

Figure 6 is a sectional view taken on line 6-6 of Figure 1,

Figure 7 is a sectional of Figure 3,

Figure 8 is a sectional view taken on line 8-8 of Figure 4, and

Figure 9 is a sectional view taken on line 3-3 of Figure 2.

In the accompanying drawings as above enumerated and in the followingspecification, like characters of reference indicate like partsthroughout and in which l2 refers to my improved window or other screenor shade and which consists primarily of a series of vertically hungslats 13, I4, which slats are of a desirable width and so spaced thatwhen the shade is completely closed the edges of slats i3 and 14 areadapted to overlap as indicated by dotted lines IS, in Figure 1 of thedrawings. The lower ends ll of said slats are connected by a flexiblecord or other member l'l.

Mounted adjacent the upper portion l3 of a window opening l9, doorway orother support is acasing 20, extending lengthways thereof into the openbottom portion 2!, the upper end 22 of each of said slats l3, l4,extends, and to which view taken on line 1-1 2 ends are securedvertically disposed hangers 23, which project up between the centrallydisposed vertical flanges 24 and 25 projecting from the top wallportions 26 and 21 or the casing 20.

The upper ends 23 of each of the members 23 form pintles upon which thecross arms 23 and 33 of a toggle member 3| are pivotally connected, theterminals 32 and 33, and 34 and 35 of which arms being pivotaliyconnected to like adjoining members. The upper edges 36 of the saidslats l3 and H are connected by a tape 31.

To an eye 38, on the terminal end 33 of the toggle member 3|, isattached one end of a cord or cable 40, which is trained over a pulley(not shown) at the opposite side of the casing and returned, threadedthrough a tube 4|, in the frame member 43, and then dropped down as at43, and terminates in a knob 44. Also secured to the eye 38, is one end45 of a cord 43, threaded through a tube 41, in said frame member 42,and dropped to a terminating knob 48. By pulling down on the knob 44,the cable will draw the toggle member to a closed position as indicatedin Figure 7 of the drawings and the slats l3 and H to an unscreeningposition as indicated in Figure 3 of the drawings, or upon drawing downupon knob 48, the member 3! will be drawn to a closing position for theslats as indicated in Figures 2 and 6 of the drawings.

Each of the terminals 28 have secured thereto one end of a spring 43,the other end of which is secured to a pivot member 50, which springsare so tensiqned as to normally cause the slats l3 and I 4, to lap uponone another as indicated in Figure l of the drawings. However, there isattached to the end ii of tape 31, an end 52 of a cord 53, which isthreaded through a tube 54 in the frame member 55, and has attached toits lower end a knob 56. This cord 53 is provided with a series of knots51, suitably spaced and for engagement by a forked bracket 58, wherebythe slats l3 and I4 may be adjusted to any desired angle relative to theplane of the screen, as indicated, for instance, in Figure 6 of thedrawings. The upper edges 59 and 60 of the flanges 24 and 25. formrunners upon which the member 3|, is slidably seated.

From the foregoing it will be seen that I have provided a practical,useful and inexpensive window shade, alcove screen, or wall partitionfor the separation of ofllce rooms and the like, a screen which may bever ornamental, one'which will completely close an opening or partiallyclose the same, or which can fully cover an open space and shut outcompletely the opposite side, and outside a clear understanding of theinvention after considering the description in connection with thedrawings. Therefore, a more lengthy description is regarded asunnecessary.

Minor changes in shape, size and arrangement of details and parts suchas come within the purview of the invention claimed may be resorted to,in actual practice, if desired.

. Having now described my invention, that which I claim as new anddesire to procure by Letters Patent is:

1. A screen formed of a series of vertically sus pended slats, means foropening and closing the same, means whereby the slats will normallyoverlap when in operative position, means whereby said slats may be heldangularly adjusted in said operative position, a toggle device fromwhich the slats are pivotally suspended, said overlapping meanscomprising springs connecting parts of the toggle member, said firstmentioned means including pull cords connected to the toggle for openingand closing the screen. and said last mentioned means including a pullcord for controlling the angularity of the slats.

2. A screen formed of a series of vertically suspended slats, means foropening and closing the same, means whereby the slats will normallyoverlap when in operative position, means whereby said slats may be heldangularly adjusted in said operative position, a toggle device fromwhich 5 the slats are pivotally suspended, said overlapping meanscomprising springs connecting parts of the toggle member, said firstmentioned means including pull cords connected to the toggle for openingand closing the screen.

10 3. A screen formed of a series of vertically suspended slats, meansfor opening and closing the same, means whereby the slats will normallyoverlap when in operative position, means whereby said slats may be heldangularly adjusted in said 15 operative position, a toggle device fromwhich the slats are pivotally suspended, and said overlapping meanscomprising springs connecting parts of the toggle member.
